This collection from the UK's Institute of Physics presents findings from academic literature about the varied ideas young people have regarding processes in the physical world. It classifies common misconceptions, easily searchable by topic and age level. Links are then provided to lessons, labs, and strategies intended to specifically address an identified misconception and introduce methods for helping students build more sophisticated understandings. Some topics include diagnostic assessments to gauge conceptual understanding prior to instruction. Users may also browse reference materials and click to view spreadsheets with in-depth data points.
